With an almost full-strength squad at his disposal, VfL Wolfsburg coach Valerien Ismael has announced that he will make changes for Saturday's game against Hertha Berlin, and the Frenchman could even switch from a 4-2-3-1 formation to a 3-5-2. Julian Draxler missed Wednesday's training session with a minor groin problem, and could be replaced by Maximilian Arnold or Daniel Didavi in the number 10 role if he fails to recover in time.
